A lot of the value I get out of Twitter is the "microblogging" aspect in which people post a quick link to a useful or meaningful or funny web page. Sure, Twitter can help you stay up to date on those you "follow," but it's also a great data mining tool. In the same way blogs allow you to plug into the brains of interesting people, Twitter allows you a micro version of this technique. In some ways, Twitter has some advantages over blog reading/writing:
As GTD creator David Allen recommends, I'm constantly striving to consolidate my inboxes (having as many as I need and as few as I can get away with). Rather than subscribe to a ton of email newsletters and clutter that inbox, I prefer to let Google Reader take care of the information I want to keep up with.
Twitter, in effect, is just one more inbox to deal with. It's yet another stream of incoming data that you must process. As with any inbox, an honest evaluation of its value and how it might be consolidated should be made.
If you follow very many people on Twitter, the amount of traffic that streams by your consciousness is mind-boggling. There's not enough time to read all of the "tweets," let alone all of the pages they point to.
As pointed out in a comment by Morten Skogly, you can access the favorites of any user as an RSS feed. This can be useful for really tapping into someone's brain. Instead of hearing all of the noise they put out, you can use them as a filter by monitoring what they value.
Just use the following pattern for an RSS feed of a Twitter user's favorites:
http://www.twitter.com/favorites/username.rss
Substitute the actual name of the user for "username" in the link above.
Taken a step further, you can subscribe to your own favorites using the same technique. This allows you to quickly tag something in Twitter as a favorite, while using Google Reader (or other news aggregator) as your "command center" for all things RSS! So tag your favorite tweets using the star, and it will show up for your later review in Google Reader.
